I am a software developer that is new to this list.
I understand that currently round-robin is the only implemented path selector
type. I am scoping (for a major storage vendor) the effort required to implement
additional selector types, as well as other work required to function properly
with their hardware (possibly special device-specific hardware handlers, config
file changes, etc.). I assume there is a procedure in place to allow developers
to submit changes such as these to the public domain, and hope that eventually
they may be included in some future distributions.

My questions are:

What is the procedure for submitting kernel
patches for the device mapper?

Who (or what organization) owns responsibility for
the device mapper kernel modules?

Who owns responsibility for the user-space
multipath pieces?

Is anyone else currently developing additional path
selector types?

I am sorry if my newbie questions are naive, but
any help to point me in the right direction will be greatly
appreciated.
